FLOW CONTROLS
HEC12-32 Pressure Compensator, Flow On Demand
DESCRIPTION
A screw-in, cartridge-style, load-sense, flow-on-demand, pressure compensator
valve.
OPERATION
With inlet flow at port 2, the HEC12-32 will deliver required flow at port 3, regardless
of load pressure sensed at port 1. NOTE: For greater stability, it is recommended to
install the 10.53 mm (0.21 inch) orifice in the load sense line at port 1.
FEATURES
• Hardened parts for long life.
• Quiet, modulated response.
